The State Analysis of Five-axis NC Machine with Large Torque Mechanical Spindle Based on Hilbert Transform
Abstract
Only five-axis machine with large torque mechanical spindle is capable to complete the process of titanium alloy aerospace structure in general. But mechanical spindle is too complex to locate the fault rapidly when the part shows anomalies or damage, and this reduces high-value machine’s utilization rate as well as brings difficulties in solving part’s quality problems. Pointing at surface quality problems and spindle component’s wearing down that emerge frequently, this paper simulates various parameters in NC(numerically controlled) machining process and monitors spindle states of a five-axis machine with large torque mechanical spindle, then amplitude, time-frequency, and frequency curvature characteristics of the tested signals are obtained by Hilbert Transform and fast identification of key component’s wearing down is realized. The results show that the state analysis method of five-axis NC machine with large torque mechanical spindle based on Hilbert transform presented in this paper has strong engineering application value.
